Enniskillen was a United Kingdom Parliament constituency in Ireland (now in Northern Ireland, which remains part of the United Kingdom), returning one MP. It was an original constituency represented in Parliament when the Union of Great Britain and Ireland took effect on 1 January 1801.
1 Walker (like F. W. S. Craig in his compilations of election results for Great Britain) classifies Tory candidates as Conservatives from 1832. The name Conservative was gradually adopted as a description for the Tories. The party is deemed to be named Conservative from the 1835 general election.
